The invention describes syntheses and purifications of several perfluorocarbon-soluble compounds having a general formula RF - L - X or RF - L - X - L - RF, wherein RF is a perfluorocarbon group, X is a hydrophilic moiety, and L is an amide linkage of general structure -CO-NH-. The invention also provides microemulsions comprising a PFC forming an oil phase, water or aqueous solution forming a water phase, and a PEG-based fluorosurfactant with an HFB (hydrophilic groups to fluorophilic groups balance) value from about 7 to about 13. The invention also provides a method of amidification of a fluorocompound. The method involves mixing perfluoracid chloride of a general formula CnF2n+1COCI with a compound containing an amine group with a general structure R-NH2 under reaction conditions sufficient to obtain a product having a general formula CnF2n+1-CONH-R.
该发明描述了合成和纯化几种可溶于全氟碳化合物的化合物,其通用式为RF - L - X或RF - L - X - L - RF,其中RF是全氟碳基,X是亲水基团,L是一般结构为-CO-NH-的酰胺键。该发明还提供了微乳液,包括形成油相的PFC,形成水相的水或水溶液,以及具有HFB(亲水基团到亲氟基团平衡)值约为7至13的基于PEG的氟表面活性剂。该发明还提供了一种氟化合物的酰胺化方法。该方法涉及将通用式为CnF2n + 1COCI的全氟酸氯与含有一般结构为R-NH2的胺基团的化合物在足够的反应条件下混合,以获得通用式为CnF2n + 1-CONH-R的产物。

The present invention provides improved compositions and methods for the collection of stem cells from an organ, e.g., placenta. The invention provides a stem cell collection composition comprising an apoptosis inhibitor and, optionally, an enzyme such as a protease or mucolytic enzyme, vasodilator, necrosis inhibitor, oxygen-carrying perfluorocarbon, or an organ preserving compound. The invention provides methods of using the stem cell collection composition to collect stem cells and to preserve populations of stem cells.
Oil-in-water emulsions in which the oil phase comprises condensed or dissolved oil-soluble gas/fluid or gas precursor are useful as ultrasound contrast agents. Such products contain insignificant amounts of free gas bubbles or microbubbles in their stored form and exhibit good stability, but may be designed to promote rapid microbubble generation immediately before or upon administration.
